Anton Khirnov dfc2c4d900 lavf: use designated initialisers for all (de)muxers. 
It's more readable and less prone to breakage.

Mans Rullgard add41decd9 Remove return statements following infinite loops without break 
These statements cannot be reached and are thus not needed.
This removes a number of compiler warnings.

Vladimir PantelicandReinhard Tartler 69fa23961e asfdec: do not fall back to binary/generic search 
asf_read_seek() inside the asf demuxer already does the
right thing, it tries the index and if that fails it uses
binary search. If binary search is called from outside of asfdec.c
it will fail because the asf code cannot clean up after itself.
Therefore introduce AVFMT_NOBINSEARCH that prevents the seek
code to fallback to binary search and AVFMT_NOGENSEARCH that
prevents the seek code to fallback to generic search.

Uoti UrpalaandRonald S. Bultje 0bd433a916 asfdec: fix assert failure on invalid files 
Add an extra size validity check in asf_read_frame_header(). Without
this asf->packet_size_left may become negative, which triggers an
assertion failure later.

Max HornandLuca Barbato ca402f32e3 handle malloc failures in ff_get_wav_header 
ff_get_wav_header is reading data from a WAVE file and then uses it
(without validation) to malloc a buffer. It then proceeded to read
data into the buffer, without verifying that the allocation succeeded.

To address this, change ff_get_wav_header to return an error if
allocation failed, and adapted all calling code to handle that error.

get_buffer         -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.
